775. Eupithecia implicata Walk. 



P.popiUataa,nd G. cxsiata are recorded by Packard from Labrador. These, 

 with the other species of Petrophora, are probably circumpolar ; they 

 afford an instance of variable species inhabiting a wide area, the va- 

 rieties not giving rise to distir.ct new species, but rather to local races. 

 Butler ("Papilio," 1881, p. 222) has expressed some doubt as to whether 

 the American species called "casuite" is identical with that of Europe.
